Potter CoilKeeper™ Solenoid Supervisory Switch

Features Coil monitoring on preaction deluge system solenoids Ability to show coil state through simple LEDs Detects open and shorted coils Can be mounted at the solenoid or remotely Provides visual indication of coil and the releasing circuit status document contains important information on the installation operation of the Coil Supervisory Switch Please read all carefully and notify the building owner or their representative before any work is done on the fire or fire alarm system A copy of this document is by NFPA 72 to be maintained on site CoilKeeper Supervisory Switch CSS is designed to supervise the of a coil on a solenoid for a preaction deluge system as required NFPA 13 The unit monitors the coil electronically and determines if coil is installed on the valve stem If a technician removes the coil the stem the CoilKeeper will activate a normally open set of dry that can be wired to a supervisory circuit of the releasing control LEDs at the CoilKeeper shows when the coil is in a normal state the valve body when the coil is removed from the valve body in maintenance state when the releasing circuit is energized and if the is open or shorted The releasing circuit energized LED allows the to locally see the state of the circuit preventing accidental by re installing an energized coil must be performed by qualified personnel and in accordance with all national and local codes and ordinances hazard Disconnect power source before servicing Serious injury or death could result all instructions carefully and understand them before starting installation Save instructions for future use Failure to read and understand instructions could result in improper operation of device resulting in serious injury or death of explosion Not for use in hazardous
